Back in June, ESPN Insider Matt Williamson provided his positional and Top 100 overall rankings of the best players for dynasty leagues for ESPN.com's fantasy football draft kit. His updated rankings, as of August 19, appear below. Note: The player write-ups remain the same except in cases where news or other developments have changed his opinion on a player.

Tight ends rarely make a huge mark in their first NFL campaign, so it's good to buy in on guys heading into Year 2. Nevertheless, you will see some rookies sprinkled into the mix here, though the players at the top should be quite familiar to those who have played only re-draft format the past few seasons.

The only negative thing I can come up with for Graham is an unlikely scenario in which his contract situation lands him with another team moving forward. It's also worth mentioning that Drew Brees won't play forever, and that Graham does tend to get dinged up his fair share. But the hybrid tight end/receiver is tough and plays through injury, is uncoverable near the goal line and is an overall mismatch in all areas of the receiving game. He's scored 36 touchdowns in three seasons, including one per game a year ago. He's only getting better, which is frightening.

There is no one else like him in the NFL. The risk-reward proposition that Gronk poses won't be for everyone. But I am buying. Gronk's stock might be the lowest right now that it will be for the next eight to 10 years. His rapport with Tom Brady is simply outstanding. Even in the event of a QB change, Gronk is good enough that any field general should be able to utilize his talents. Also boosting his stock: Gronk is about 2½ years younger than Graham.
